klogg 0.1.6

Simple command line work logger

klogg — simple command line work logger

klogg is a small command-line tool for keeping simple timestamped work logs. It's designed to be minimal and friction-free: append entries with a single command and view per-day or per-month summaries including durations.

Project

• Name: klogg

• Author: Predrag Mandic [e-mail]

• License: MIT

Installation

From the project root you can install locally:

• Editable install (for development): pip install -e .

• Or build and install: pip install .

klogg exposes a console script named klogg (entry point: klogg.cli:main).

Log files and layout

• Default log directory: /home/peja/.config/klogg
• Monthly log files are named YYYY-MM.log (for example: /home/peja/.config/klogg/2025-12.log).
• There is also legacy support for default.log.

Log line format

Each log line is written with a timestamp and the message:

YYYY-MM-DD HH:MM:SS>

Example: 2025-12-15 11:15:00> Fixed the widget

Special markers

• — marks the start of a session (the line itself is not shown in summaries; it acts as a starting timestamp for the next entry).
• — marks a short break. Break entries are excluded from total time calculations.

Commands

When you run klogg without a subcommand it behaves like klogg day and shows today's entries.

Common commands:

• klogg --help Show usage and available commands and options.

• klogg --version Print the installed klogg version.

• klogg add (alias: klogg a ) Append a timestamped log line with the given message. Example: klogg add Fixed the widget

• klogg break [message] (aliases: b, p) Append a break entry. If you pass a message it becomes: " " Example: klogg break grabbed coffee

• klogg start (alias: s) Append the literal "" marker.

• klogg ls [WHEN] Print raw log lines for a month. WHEN formats accepted:

  • YYYY-MM (exact month)
  • MM (assumes current year) If omitted, shows the current month's raw lines.

• klogg day [WHEN] (alias: d) Show parsed entries for a day with durations and totals. WHEN accepted:

  • YYYY-MM-DD
  • MM-DD (assumes current year)
  • DD (assumes current month & year)
  • -N (negative integer, e.g. -1 for yesterday; when passed as a positional argument it must be prefixed with -- so the CLI doesn't treat it as an option: klogg day -- -1) Output format: YYYY-MM-DD HH:MM:SS [HH:MM]> MARKER_AND_DESCRIPTION The total excludes entries that begin with "".

• klogg week [WHEN] (alias: w) Show parsed entries for an ISO week with durations and a total. WHEN accepted:

  • WW (week number, assumes current year)
  • YYYY-WW (year-week, e.g. 2025-52)
  • -N (negative integer, e.g. -1 for previous week; when passed positionally use -- as in klogg week -- -1) Weeks follow ISO week numbering (date.isocalendar()), so week 1 is the first ISO week of the year.

• klogg month [WHEN] (alias: m) Show parsed entries for a month and a total. WHEN accepted:

  • YYYY-MM
  • MM (assumes current year)
  • -N (negative integer, e.g. -1 for previous month; when passed positionally use -- as in klogg month -- -1)

• klogg rm Remove the last log entry from the most recent log file. The command prints the last entry and asks for confirmation before deleting.

Behavior notes

• Each appended entry uses the current timestamp as the "end time" for the task. Durations are computed as the difference between an entry's timestamp and the previous entry's timestamp.
• The "" line is not printed in day/month summaries; it only sets the "previous timestamp" for the next entry.
• Breaks ("") are printed but excluded from the totals.

Development notes

• Python: requires >=3.8
• Dependencies:
  • click >= 8.0
  • click-aliases >= 1.0
